- 7. Downloading Information from the TP3PCAS Using a CF Card
- 1. Obtain a New or Blank Compact Flash (CF) card.
- 2. Copy to the New or Blank CF card the appropriate ‘Header File’
- a) Header files are files copied to the New or Blank CF card that will instruct the computer unit what is desired to be downloaded.
- b) Header files needed to download Maintenance Data, Event Data and CRC Part Numbers can be obtained from ACSS Customer Services at +1-623-445-7070 or crc.acss@l-3com.com.
- 3. For downloading Maintenance Data, Event Data or CRC Part Numbers the aircraft does not need to be in an on-ground configuration.
- 4. Apply power to the computer unit.
- 5. Insert the CF card.
- 6. For ACSS part numbers 9005000-10000, -10101, -10202, and -10204 the DATA STATUS LED will UblinkU green once; this indicates the unit recognized that a CF card was inserted.
- 7. For ACSS part numbers 9005000-11203, -11801 and -55801 the DATA STATUS LED will UblinkU green while reading the header file and performing the action defined in the header file.
- 8. Flight Data Recording
- 1. T3CAS part numbers 9005000-10000, -10101, -10202, and -10204 only support FAT16 CF card formatting. T3CAS part numbers 9005000-11203, -11801 and -55801 support both FAT16 and FAT32 CF card formatting.
- B. Flight Data
- 1. Obtain a New or Blank CF Card.
- 2. Copy to the New or Blank CF Card the Appropriate Header File.
- 3. Header files are files copied to the New or Blank CF card that will instruct the computer unit what is desired to be downloaded.
- 4. For Flight Data Recording, the aircraft does not need to be in an on-ground configuration.

Designation
Functional Description
J1-26
ARINC 429 (A) TCAS TA/RA DATA INPUT:
Traffic and Resolution Advisory data is supplied to the VSI-TCAS from the T
3
CAS
computer unit via this high-speed ARINC 429 data bus. Paired with pin 11.
J1-27
ARINC 429 (A) VERTICAL SPEED NO.1 INPUT:
This is the primary ARINC 429 input bus to the VSI-TCAS. This pin accepts high-
or low-speed ARINC 429 vertical speed data (Label 212). Its use is determined by
the source select discrete and configuration straps CS0 and CS1 (pins 31, 32, and
33 respectively).
Paired with pin 12.
J1-28
CONFIGURATION STRAP #2 INPUT (NO):
This is the V/S response time selection. A time constant of 3.8 sec with pin 28
open and of 7.6 sec with pin 28 grounded.
J1-29
TA/RA VALID DISCRETE OUTPUT (NO):
This output discrete indicates the ability of the VSI-TCAS to perform as a resolution
advisory and/or a traffic advisory display. If the VSI-TCAS fails, this discrete
presents an open. Normal operation causes a ground. This discrete is monitored
by the T
3
CAS computer unit.
J1-30
ARINC 429 (A) VERTICAL SPEED NO.2 INPUT:
This is the secondary ARINC 429 input bus to the VSI-TCAS. This pin accepts
high- or low-speed ARINC 429 vertical speed data (Label 212). Its use is
determined by the source select discrete and configuration straps CS0 and CS1
(pins 31, 32 and 33 respectively). Paired with pin 14.
J1-31
(Continues)
SOURCE SELECT DISCRETE INPUT (NO):
This discrete input is used in conjunction with configuration straps CS0, CS1 and
CS2 to program the VSI-TCAS to accept and use the vertical speed data being
supplied. In some installations, this discrete is connected to a switch in the Flight
Deck and is used to select between primary and secondary ARINC 429 vertical
speed inputs. It is hard-wired to configuration strap common if ac or dc analog
vertical speed inputs are used. Cycle power to update to the new configuration.
The following applies: O = Open, G = Ground.
